I've been using Firefox for many years (never been a fan of Chrome), but the most recent update broke it's integration with "KeepassX". I prefer KeePassX to "KeePass2.0," because it doesn't require "mono" or any other MS code. Basic "KeepassX" isn't capable of integrating with any browser, but there are some branches (https://github.com/k...reboot/keepassx) that interface through "PassIFox." Updating to "Firefox 49" broke this integration (ie username and password no longer automatically loaded on opening a site's login page). I tried several other browsers like "Chrome" (again) and "Seamonkey," that would support KeepassX, and finally settled on "Palemoon." Palemoon is fast. It seems to load pages pretty much as quickly as I can press "enter."
In addition to supporting "KeepassX " through "PassIFox," Palemoon also supports the other security add-ons I use either through Palemoon versions like "Encrypted Web" (HTTPS Everywhere) and "Decentraleyes X.X.X-palemoon," or through regular Mozilla add-ons like "uBlock origin" and "Disconnect," It also accepts "Startpage" as an alternate search engine. Once I added "Palemoon Linux 3.0" and "Foobar," transferred my bookmarks as a saved HTML, and futzed around with "preferences" and "about:config" for a while I ended up something that looks and acts very much like the secured "Firefox Australis" I was replacing, with the advantage of being much more responsive. I've been using it for about a month now and I'm very pleased. I'm so pleased I'm thinking of moving from "Thunderbird" to Palemoon's "FossaMail."
I have to admit that Jame's earlier comment , "There is some debate on their security level as being ran mostly by one guy, but a whole team does contribute." was something that gave me pause when I first considered Palemoon. However, I rationalized, "couldn't I say the same about "Bodhi?"
If anyone wants to install a reasonably secure version of Palemoon to replace Firefox or Chrome you could probably use this post as an outline. I'd also suggest that you consider subscribing to a secure anonymous VPN. If I move to FossaMail I'll try to write a similar post on the install and customization. I'm also considering moving to Palemoon's sync service. I find the fact that (in addition to username/password credentials) palemoon sync both encrypts synced data before sending and decrypts that synced data only on my machine with a key that remains on my machine is very attractive from a security viewpoint. I'll also let folks know how this works out.
I suppose my emphasis on security might make me appear like a member of the "Tin-Foil Helmet Brigade," but since Snowden we do know that they're watching all of us at least generally. None of the add-ons I'm using are difficult to install, nor do they adversely affect my browsing. I can't see any reason that I should make it easy for the various Business and Government busybodies. If everyone made the snoopers job just a bit more difficult, then mass surveillance might become prohibitively difficult and expensive. End of Rant.
